Mask problem

Hi,

I made something (glint tutorial) and from Library dragged in main timeline. In Library everything works fine, but doesn’t running SWF.

I have some text (for button) and one rectangle with gradient fill.
The text is mask. Running SWF this rectangle gradien are visible
and covers text.

I need that glint to be visible everytime mouse is over the button.

Why this effect works in Library but won’t work in main timeline?

Thanks in advance.
